1N5238C-TR

Single Zener Diodes Overview

The Vishay 1N5238C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides an 8.7 V nominal Zener voltage with a ±2% tolerance, as indicated by the 'C' suffix. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum dynamic resistance of 8 Ω at a test current of 20 mA, a reverse leakage current of 3 µA at 6.5 V, and a typical temperature coefficient of 0.065 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Provides tight ±2% Zener voltage tolerance for precision applications
• Features a glass-sealed DO-35 axial leaded package

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the required ±2% tolerance specification. Ensure the '-TR' suffix matches the desired reel packaging format. Cross-reference the document number 85588 to access the latest electrical parameters and absolute maximum ratings before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 8.7 V reference is required with tighter tolerances than standard variants. The DO-35 package supports through-hole mounting. Evaluate the 500 mW power dissipation limit against expected operating conditions to ensure the junction temperature remains within the specified maximum rating during continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 2.4 V to 75 V. The specific 'C' designation denotes a tighter manufacturing tolerance compared to the standard 'B' variant, making it suitable for applications requiring higher accuracy.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include the 1N5238B-TR, which offers the same electrical performance but with a wider ±5% tolerance. Other packages such as SOD-123 or MiniMELF are available for different form factors, though they require separate verification of pinout compatibility.
